D4

The D4 dozer (formerly D6K2) combines fuel efficiency with power and precision to excel in a wide range of jobs. The balanced design is optimized for finish grading. To boost your productivity even more, choose from a variety of technology options that help you get more quality work done in less time.The D4 dozer (formerly D6K2) is smart and efficient. It comes equipped with GRADE technologies like Slope Assist and GRADE with 3D to make it easier for even less experienced operators to get more quality work done in less time. But intelligence is only part of the package – Eco Modes and a new power train deliver up to 17 percent more fuel efficiency, while providing superior maneuverability, faster steering response and greater capability to utilize full blade loads. This dozer also retains its optimal balance and undercarriage design for outstanding performance in finish grading applications.
